House presently has a 4 ton AC installed and that is sized right.
We are planning on replacing that with a 4 ton 19i Trane. All bids came in with that same size.
On reading info here and from Trane, I know the Trane 19i 4 ton has 2 compressors, a 1 1/2 ton and a 2 1/2 ton and that they cannot run at the same time. So the largest I will have is a 2 1/2 ton unit.
Am I replacing a 4 ton with a 2 1/2 ton ???? Will I be undersized ????
This is not making sense to me...............................
